What is the method causing such failure? Is the method in Resource Block or in Transducer block?
I don't have the physical Mass Flowmeter device, but I have imported the DD/CFF files (revision 02) to Configurator 3.1 version. And it looks like the methods in resource block can work properly, but not sure about the methods in transducer block.
The 3.1 version is released this month, and it is not a free upgrade, you need to order 850283-01 to upgrade to this 3.1 version.
As I know, you should have 3.0 version if you purchased in last December, because the 3.0 version was released mid of last year.
I suggest you send your PO number and other purchase information to fieldbus.support@ni.com for NI support.
